' zemimj (-01. 30-201)" I My invention relatesto. an attachment tor a hair clipper.

The prime object of my invention is to generally improve that type of hair clipper wherein a reciprocating cutter blade works upon a so-called comb which is a. stationary blade. I

Another important object of my invention is to provide an attachment for a hair clipping machine which makes it possible to adapt the clipping machine for convenient use under all circumstances and in different places. The invention aims at a hair clipper which can be easily. adjusted to cutting hair in places where ordinary hair clippers can hardly be used or only with difficulties, for instance, for cutting the fetlocks above the hoofs of a horse without lifting the legs of the horse.

More specifically, other, objects of my inven tion center about the provision of. a hair clipper attachment which can be readily locked in a desired position as well as unlocked.

Still other objects of this invention are to provide a hair clipper attachment which will embody all of the commercially desired advantages, such as simpleness and sturdiness in construction and low cost in manufacture.

Another more specific object is to provide a hair clipper attachment the fastening, adjusting and locking means of which are designed to form independent parts which can easily be added to a standard type of clipping machine to convert same into an adjustable hair clipper.

To the accomplishment of the foregoing and other objects which will hereinafter appear, my invention consists in the elements of a hair clipper attachment and their relation one to the other, as hereinafter are more particularly described in the specification and sought to be defined in the claims. The specification is accompanied by a drawing in which:

Fig. l is a bottom plan view of the front portion of a hair clipper embodying my invention;

Fig. 2 is a side elevation showing the adjustable attachment in normal position;

Fig. 3 is a fragmentary view of Fig. 2 showing the attachment in a difierent position;

, Fig. 4 is an isometric view showing parts separated;

Fig. 5 is a section taken approximately in the plane of the line 55 of Fig. 2, drawn to en larged scale; and

Fig. 6 is similar to Fig. 5, but showing a different position.

Referring now to the drawing in greater detail,

IB designates a plate having two side flanges ll 1" and carrying a stationary toothed blade l2 whi'oh will be referred to as the comb, and a toothed cutter blade I 4 reciprocating onthe comb; The

comb and the cutter blade are fastened to the flanged carrier plate I0 by'means of. screws it (see Fig. 1) In Fig. 4, I 8 indicates screw holes in the plate [0 to receive the screws l6. The plate I0 is pivotally attached to another flanged "plate at 22. The flanged plate or member 20 is fastened to the clipper frame 24 by means of screws which lie beneath the screws l 6. Again in Fig. 4, screw holesi26 are shown in the member 20. Theflange 2B of the member 20 is provided with an elongated slot generally designated 30 and'having circularly .enlargedends32, 32. In the embodiment selected for illustration, the flange 28' of the memberm has no slot. I

' It will be seen that the flanges If of theplate Ii! are in a contiguous relationship with the flanges 28 and'2'8 of the member 20.

The plate It], the comb I2 and the cutter blade M are referred to as the adjustable head or cutter head.

It will be understood that the plate H) can be swung about 22 to assume either the position shown in Fig. 2 or the position shown in Fig. 3. The plate It carries a sleeve 34 (see Figs. 5 and 6) in which a pin 36 is slidably arranged and normally held in the position shown in Fig. 5 by a compression spring 38. The inner end of this spring bears against the plate In whereas the outer end of the spring bears against a head 40 of the pin. The shank 42 of the pin 36 forms at its other end an enlarged portion 44.

It should be noted that the enlarged portion 44 is circumferentially of such a shape that the ends 32, 32' of the slot 30 are able to accommodate the portion 44. When the portion 44 is received in either of the ends 32, 32', the plate It) and, therefore, the cutter head is locked in its position (see Fig. 5). In order to unlock the plate I0, merely pushing the pin head 40 inwardly urges the portion 44 of the pin 36 inside of the flange 28, as is clearly shown in Fig. 6, whereby the thinner shank 42 of the pin is received in one of the ends 32, 32, thus allowing the shank to pass through the narrow passage 46 between the ends 32, 32' (see Fig. 4). If the cutter head is in its normal position shown in Fig. 2, the enlarged portion 44 is received in the end 32, and if it is now desired to change the cutter head position to that shown in Fig. 3, it is necessary to press the pin head inwardly with a finger of one hand, thus unlocking the cutter head to be turned, while a finger of the other hand of the user of the clipper touches the cutter head at the face 41 (see Fig. 2) and turns same outwardly in the direction of the arrow indicated in Fig. 2. Upon releasing the pin head, the spring 42 urges the pin outwardly, thus moving the enlarged portion 44 into the enlarged end 32' and locking the adjustable cutter head in the position of Fig. 3. I

It will be clear that the flange 28 may be provided with a slot having, for instance, three enlarged regions, one at each end and a third one intermediate the ends. Such a construction will make it possible to use the head in three different positions instead of two. v

From the foregoing, it will be seen that all of the parts which form my attachment and which, according to my-invention, serve to fasten the cutter. head to a hair clipper and make the adjustment of the cutter head and its looking in any desired position possible, are simple in construction, inexpensive to manufacture, easy to mount on a standard clipper, and easy and quick to operate.

It is believed that the construction and operation, as well as the many advantages of my improved hair clipper attachment, will be ap: parent from the foregoing detailed description thereof. It will also be apparent that while I have shown and described my invention in a preferred form, many changes and modifications may be made in the structure disclosed without departing fromthe'spirit of the invention.

I claim:

1. Attachment for replacing the comb blade and reciprocating cutter blade of a hairclipper comprisinga flanged plate serving as a supportgated slot in at least one of the flanges of the supporting plate, and at least one spring-pressed pin carried by a flange of the carrier plate and including a shank and an enlarged portion, said slot having enlarged ends, said enlarged poring member, means to fasten said supporting plate to the clipping head in place of said retion being adapted to be normally received in one of said enlarged ends, the shank, on pushing the pin. and compressing the spring, being enabled to pass from one enlarged end to the other.
